Thanks! Your car looks AMAZING!
Yeah, I figured not everyone knows the story behind them and/or knows how they mount. They basically have a hubcentric ring that the hex cap presses into place. They even have some relief areas on the fan "blades" for optimal balance. These are really well put together, just like the originals. I've had them on the car for a mix of backroads and highways and they stay silent, don't move, and don't contact the wheel lips or faces.
Thanks! Definitely a fun addition with a bit of a story and some relevant history.
